+\S2{using-cmdline-hostkey} \i\c{-hostkey}: \I{manually configuring
+host keys}manually specify an expected host key
+
+This option overrides PuTTY's normal SSH host key caching policy by
+telling it exactly what host key to expect, which can be useful if the
+normal automatic host key store in the Registry is unavailable. The
+argument to this option should be either a host key fingerprint, or an
+SSH-2 public key blob. See \k{config-ssh-kex-manual-hostkeys} for more
+information.
+
+You can specify this option more than once if you want to configure
+more than one key to be accepted.
